morePlasma levels of ethanol and acetate, which is the end product of hepatic ethanol oxidation, have been studied in 60 rats. Animals were divided into two groups: 1) Control rats, and 2) Alcohol-treated rats. Ethanol and acetate were measured without any previous handling (endogenous levels) and after intraperitoneal injection of a single dose of ethanol. Blood specimens were taken at 30, 60, 120, 180 and 240 minutes after ethanol injection. Plasma levels of ethanol and acetate were performed by Head Space Gas Chromatography. Alcohol-treated animals had higher plasma acetate levels than control ones. There were statistically significant differences for acetate between both groups of rats at 0, 30, 120 and 180 minutes.
We have compared the individual sensitivity, specificity and predictive value of the CAGE questionnaire, plasma levels of ethanol and acetate, mean corpuscular volume (MCV), gamma glutamyl transferase (GGT), and glycosylated haemoglobin...
moreWe have compared the individual sensitivity, specificity and predictive value of the CAGE questionnaire, plasma levels of ethanol and acetate, mean corpuscular volume (MCV), gamma glutamyl transferase (GGT), and glycosylated haemoglobin (Hb A1c) in a group of 50 healthy non-alcoholic controls and 31 patients with non-alcoholic liver disease (Group I), and in a second group of 40 alcoholic patients (Group II). Taken individually, the CAGE questionnaire was the most efficient (96% sensitive and 92% specific), followed by plasma levels of acetate (74% sensitive and 85% specific), MCV (64% sensitive and 91% specific) and GGT (72% sensitive and 80% specific). Hb A1c did not show any statistically significant difference between alcoholics and non-alcoholics and thus is of no use as a screening test for the diagnosis of alcoholism. Furthermore, we attempted to design a discrimination procedure to separate alcoholics from controls and patients with non-alcoholic hepatic diseases using a com...

moreABSTRACT From the legal point of view, informed consent is the main exponent of the principle of autonomy. However, the patient's informed consent should be raised as the corollary of a doctor-patient relationship based on mutual trust, and not simply as a proof for the exemption of the physician liability. The requirement of informed consent is underdeveloped in the field of Rehabilitation. In this article we review the concept of informed consent, the key points (who should be informed, how much information should be disclosure and if the information should be given orally or in a writing form) and what still remains to be done in Rehabilitation. We express a personal opinion about protocols on written consent forms for some procedures; those who are but not needed and those who are missing.

moreA diagnosis of drowning is a challenge in legal medicine, as there is generally a lack of pathognomonic findings indicative of drowning. Diatom analysis has been considered very supportive for a diagnosis of drowning, although the test is still controversial for some investigators. We assessed diatoms association with drowning in the peripheral tissues of drowned rats and the effects of the drowning medium on the diatom yield. A modified acid digestion method was optimised for diatom recovery in water and rat tissues. Eighteen adult Wistar rats were employed for the study, subdivided into six groups of three rats. Groups 1, 3 and 5 were drowned in seawater, lake water, or river water respectively, while groups 2, 4 and 6 were controls (immersed after death in seawater, lake water or river water respectively). Water samples were taken from the sea, lake and river in Málaga and Córdoba (Spain) for the purposes of diatomological mapping and drowning of the rats. Diatoms were successfully recovered from all water samples and matched with tissues of the drowned rats. There were significant differences in diatom numbers between control and test samples for all the tissues studied, as well as within test samples. Histological investigations conducted on lung samples obtained from drowned rats provided complementary and valuable information. This study demonstrates the feasibility of the diatom test as a reliable method for the diagnosis of drowning, especially if adequate precautions are taken to avoid contamination, and if interpretation of the analysis is performed in light of other complementary investigations.

moreThe aim of the study was to ascertain the opinions of both inmates and staff of prison establishments about the use of coercive measures justified for clinical reasons for people with mental health problems and about the need to create protocols to regulate the application of these measures. These opinions were gathered in a Qualitative Study with Focus Groups (prison inmates and prison staff) from the Granada Penitentiary Centre and the Alicante Penitentiary Psychiatric Hospital, both in Spain. The results showed that forced medication is the most commonly used coercive measure in these institutions. The inmates did not understand and rejected the use of this measure, above all because they were poorly informed about their illness and the medication required to treat it. The staff however defended the benefits of psychiatric medicine, even when administered without the patient's consent. Both inmates and staff agreed that it would be useful to have a protocol regulating the use...
